Aphelion. A planet, comet or other celestial body moving around the Sun, does so in an elliptical orbit with the Sun located at one of the foci (Kepler’s First Law). This means that the distance between the planet and the Sun changes throughout the orbit.
21 maj 2024 · An aphelion is a moment in the point of a celestial body's orbit around the Sun when the celestial body is furthest from the Sun. The opposite of an aphelion is a perihelion, when that object is closest to the Sun.
Aphelion, in astronomy, the point in the orbit of a planet, comet, or other body most distant from the Sun. When Earth is at its aphelion in early July, it is about 4.8 million km farther from the Sun than when at its perihelion in early January.
Definition. Aphelion is the point in the orbit of a planet, asteroid, or comet where it is farthest from the Sun. It is one of two extreme points in an elliptical orbit, the other being perihelion.
Description: Aphelion is the point along an orbit around the Sun where the orbiting body is farthest from the Sun. Objects orbiting the Sun and not affected by any other object have orbits with an elliptical shape with the Sun at one of the foci of this ellipse. Mathematically, aphelion marks one end of the major axis of the ellipse.

(pl. a·phe·li·a / əfēlyə; əˈfēlēə / or a·phe·li·ons) Astron. the point in the orbit of a planet, asteroid, or comet at which it is furthest from the sun: Mars is at aphelion.

Definition. Aphelion is the point in an object's orbit around the Sun where it is farthest from the Sun. This term is significant because it plays a crucial role in understanding the elliptical orbits of planets, as described by Kepler's laws of planetary motion.
